Answer:
4620.
Step-by-step explanation:
The number of combinations of 3 men from 9
= 9!/(9-3)!3!
= 9*8*7/3*2*1
= 84 ways.
The number of combinations of 2 women from 11
= 11!/11-2)!2!
= 11*10/2*1
= 55 ways.
So the total number of ways of men and women in the committee
= 84*55
= 4620.
Answer:
s = 10
______________
To get from 4 to 8, you multiply by two. Because the triangles are congruent, you would do the same thing with 5 to S. 5 * 2 = 10. So S = 10

Answer:
Test:
< 20 with normal distⁿ
Hypothesis test:
H0:
20 (Null Hypothesis, H₀ :
= 20 is also correct)
H1:
< 20 (Alternative Hypothesis, also called H₁)
This is lower tailed test.
Since sample is large, sample standard deviation can be taken as an approximation of population standard deviation.
x = 19.3
= 11.1
n = 444
significance level,
= 0.05 (If no value is given, we take level of 0.05)
Test statistic 

= - 1.33
